A new approach of online waste removal process for laminated object manufacturing (LOM)

A new online de-cubing laminated object manufacturing process which employs self-adhesive sheet with shielding paper is proposed in this paper. The main idea of this new process is to perform bond-then-cut at the same position, avoiding the accumulated error resulted from reposition, and to de-cube the inner waste material in process by peeling off the shielding paper. By doing so, about 30–80% waste material according to various geometric shapes can be removed during the machining process. The new process not only shortens the time for laser cutting and de-cubing, but also enables the production of hollow and shell-shaped parts. Hence, the proposed process promotes both the performance efficiency of laminated process and the manufacturing ability regardless the geometry of the parts.
